Nike Vaporfly 4 Men's Road Racing Shoes

Key Specifications

• Midsole Foam: Ultra-lightweight and springy Nike ZoomX foam providing pinnacle energy return without a mushy, "marshmallow" feel.

• Propulsion System: A redesigned full-length carbon fiber Flyplate featuring a 3% increase in curvature to generate a snappier, more forced forward lever during toe-offs.

• Stack Height & Drop: Stripped down to a lower profile 35mm heel / 29mm forefoot stack layout with a natural-feeling 6mm heel-to-toe drop.

• Weight: Incredibly featherlight at just 190 grams (6.7 oz) for a standard men's US 10, cutting roughly 10% of the weight from its predecessor.

• Upper Construction: A re-engineered, highly breathable Flyknit upper built on an updated last that provides a slightly wider, more accommodating midfoot fit.

• Outsole: Reconfigured with continuous forefoot rubber coverage reminiscent of earlier generations to maximize cornering traction and high-speed grip.
